PrimaLuna wanted to make owning a tube amp so simple you would have no excuse not to have your tube dreams come true.

Triode and Single Ended Triode (SET) amps are popular for their warmer, fuller, and easy to settle into sound. But triode amps have limitations! Ultra-linear has more extension on the top and bottom, not to mention greater power. They have greater “pop” with a bigger difference between light and dark, and loud and soft. Having triode only is very limiting. The best option is to have both triode and ultra-linear. PrimaLuna in Holland designed an ingenious circuit that lets you change from triode to ultra-linear with a push of a button on the supplied remote control.

No need to get up and stop the music. Make an instant comparison while you listen and choose what you like best for that song or album. DiaLogue Premium is about goose bumps. The ones you get when music comes out of a background so quiet, you may say to yourself “Just how is this possible?” PrimaLuna custom-winds our their massive toroidal power transformers that are low in hum and EMI. But we wanted more. PrimaLuna designed the AC Offset Killer to lower transformer noise to a place no other manufacturer dreams of going, regardless of how bad your electricity is. The result? Sense of space. Texture. The resonance of an acoustic guitar or violin string that seems to trail on forever.

If a tube fails, Adaptive AutoBias will instantly put the amplifier into protection mode so no parts can get damaged. A red LED will light up in front of the tube that needs replacing. Simply plug in another tube, and listen. No guesswork. No smoking amp. No getting out the soldering iron or dropping your amp off at UPS. Easy to identify through their pink color, resistors from Takman Japan are popular with those who rebuild and upgrade their gear. Mundorf Mcap Evo Silvergold capacitors made in Germany are used in the critical signal paths and while they are expensive, the PrimaLuna team felt they could not be left out after careful listening comparisons with many different types.

All PrimaLuna products use massive, potted toroidal transformers. PrimaLuna transformers are enclosed in a metal housing and then potted in a non-microphonic resin to further reduce noise and to protect the windings from moisture and deterioration forever. Price: $3,899 single, $7,798 pair. Power: Mono Ultra-linear (8 Ohms, 1% THD) 148 watts (EL34). With PrimaLuna, you get to choose. Go for it. 6L6G, 6L6GC, 7581A, EL34, EL37, 6550, KT66, KT77, KT88, KT90, KT120, even the monstrous KT150.
